There are a number of third party apps available to offload this from Exchange. Both of my University clients use a third-party app for conference room scheduling because of the overhead. But I agree with Rob - get a bigger bag, or remove some $41*. Regards, Michael B.

From: Paul Wehner [mailto:pweh...@nd.edu]<mailto:[mailto:pweh...@nd.edu]> Sent: Thursday, September 22, 2011 8:23 AM To: MS-Exchange Admin Issues Subject: exchange 2007 hail mary Importance: High I'm at the end of my rope and ready to tie the other end to a tree and would appreciate any advice We have 5 exchange 2007 SP2 CCR servers w/ about 16K mailboxes (4.3TB edb's) The problem we have is that periodically one of active nodes will stop responding and all users will disconnect. 'Resolution' of the outage has been to move nodes. This issue affected 2 of the 5 servers. some databases on these boxes were +400GB. I've created new smaller databases, deleted the larger, moved mailboxes, etc but all that's apparently done is transfer the problem to previously 'good' mailbox servers. Issue occurs at least 3 times a week- always during peak times. At times average RPC Latency has shot up to over 1600 We have 9 cas servers- 5 are 2007, 4 are 2010 (we have a small dev 2010 presence) Pop/Imap are available to all via F5 load balanced host- no special config made to the service. Half of physical memory on cas is used by imap and IIS Everything sits behind ISA. Why I think this problem is occurring: I run expba regularly and have scom monitoring. It's common to get RPC latency and high memory warnings on cas and mailbox. Quota's are enabled but not enforced. Mailboxes start a 1 GB and some have 10-15GB used. We have perhaps 1500 mailboxes with +20-60k items in Inbox. %70 of all activesync users sync with more than 2 devices- some have 4. More than %60 of mailboxes connect/sync with multiple email clients We have about 100 conference room mailboxes with an avg. of 8 users granted "full" rights. Some conference rooms have more than 30 owners. Some people set up 5-10 delegates. Apparently it's common for depts. here to have admin staff responsible for trolling calendars to track down people and appt. locations. (many people here believe the only way to schedule or view is to File>Open- resource cal) when Exchange was first rolled out 3 years ago this high calendar use caused rolling brown outs due to clients blowing through msExchMaxCachedViews. MS informed us we could raise this to 30 and warned us not to do so, and attempted to communicate best practices info. We did it anyway. I'm in the process of updating all servers to 2007 SP3 RU4. thank you for any advice Paul --- To manage subscriptions click here: http://lyris.sunbelt-software.com/read/my_forums/ or send an email to listmana...@lyris.sunbeltsoftware.com<mailto:listmana...@lyris.sunbeltsoftware.com> with the body: unsubscribe exchangelist ************************************************************************************************** Note: The information contained in this message may be privileged and confidential and protected from disclosure.
